- Update SPIRV-Cross version to include latest argument buffer fixes.
- Disable CompilerMSL::Options::force_active_argument_buffer_resources.

- Track OpArrayLength buffer-sizes buffer as an auxiliary buffer in each
  descriptor set argument buffer, as this is how SPIRV-Cross expects it.

- Revert MVKConfiguration::useMetalArgumentBuffers and env var
  MVK_CONFIG_USE_METAL_ARGUMENT_BUFFERS to boolean value, because
  descriptor indexing value is not longer required.
- Update max number of buffer and textures per stage to 1M.

- Refactor and simplify calculating argument buffer resource indexes
	- Remove MVKShaderStageResourceBinding::resourceIndex,
	  and track resource index incrementing locally.
	- Update MVKDescriptorSetLayout::_descriptorCount & _mtlResourceCount
  	  from within MVKDescriptorSetLayoutBinding.

- Refactor and simplify tracking argument buffer usage
	- Rename MVKDeviceTrackingMixin::isUsingDescriptorSetMetalArgumentBuffers()
	  to isUsingMetalArgumentBuffers(), and allow it to be overridden in
	  MVKDescriptorSetLayout.
	- Move and rename MVKDevice::_isUsingDescriptorSetMetalArgumentBuffers
	  to MVKPhysicalDevice::_isUsingMetalArgumentBuffers.
	- Remove MVKPhysicalDevice::supportsDescriptorSetMetalArgumentBuffers();
	- Remove MVKDescriptorSetLayout::isUsingMetalArgumentBuffer() and replace
	  with overridden isUsingMetalArgumentBuffers() function.
	- Rename MVKDescriptorSet::isUsingMetalArgumentBuffer to hasMetalArgumentBuffer().
	- Remove MVKDescriptorSetLayoutBinding::isUsingMetalArgumentBuffer().
	- Remove MVKDescriptorSetLayout::isPushDescriptorLayout().

- Update debugging logging
	- Refactor and enhance ability to log descriptor set descriptions for debugging.
	- MVKPipelineLayout support debug logging and remove a few unused member functions.
	- Adjust whitespace in logging of instances and devices.

- Update MVK_PRIVATE_API_VERSION to version 43.
